Display screen or portion thereof with graphical user interface



The FIGURE is a front elevation view of a display screen or portion thereof with graphical user interface showing my new design.

The broken lines showing portions of the graphical user interface are included for the purpose of illustrating environmental structure and form no part of the claimed design. The dash-dot broken lines showing the display screen define the bounds of the claimed design and form no part thereof. 

CLAIM I claim, the ornamental design for a display screen or portion thereof with graphical user interface, as shown and described.
